Cryo Milling | Cryogenic Grinding
The introduction of lower temperatures during cryomilling curbs recrystallization and embrittles materials so they can be fractured more easily with mechanical milling. Cryogenic grinding is often performed in impact mills and hammer mills, but the use of an internally agitated ball mill, like an Attritor, can provide additional benefits.

Experimental investigation of the impact breakage characteristics
Since the advent of ball mills, the research of particle breakage properties has always been a hot topic. In the milling process, the particle breakage process is like a black box, and hard to quantify the breakage behavior. In fact, the particle breakage property (size reduction) is a key factor, which directly affects the grinding effect.
